SUMMARY:Andrew HARVEY (University of Cambridge) " Speculative markets: bubbles or balloons?"
DESCRIPTION:[vc_row][vc_column][vc_column_text]Finance & Financial Econometrics : \nTime: 11.00 am\nDate: 28th of November 2024\nRoom 3001 \nAndrew HARVEY (University of Cambridge) “Speculative markets: bubbles or balloons? ” \nAbstract : Speculative markets may be characterized by sharp falls after a slow build up. Sometimes the converse happens. We suggest a number of mechanisms that are able to produce this kind of behaviour and we demonstrate their plausibility by simulation. The models are then fitted to daily data on Bitcoin. In constructing these models we show that it is essential to take account of volatility and non-normality. We also investigate the possibility of a dynamic tail index. The conclusion\, at least for Bitcoin\, is that speculative\nmarkets are more likely to behave like balloons\, where there is rapid inflation followed by a slow decline\, rather than like bubbles. \n \nOrganizers: \n\nJean-Michel ZAKOIAN (CREST) \nSponsors:\nCREST[/vc_column_text][/vc_column][/vc_row]\n
